If the rise of social media — and specifically the explosion of “viral” content on networks like Facebook and Twitter — has done nothing else, it has certainly given mainstream media plenty of “user-generated content” to add to their dwindling repertoire of journalism. Almost every newscast seems to include a video of cute animals or some other clip that is making the rounds on the social web. Unfortunately, no one seems to care much whether any of these videos are real or not, and that is a very real problem.
